Aberasi kromatis
Definition & Context
Noun
A word that functions as the name of a specific object or set of objects, such as living creatures, places, actions, qualities, states of existence, or ideas.
An optical defect in lens systems where light of different wavelengths is refracted at unequal angles, producing colored fringes or halos around the edges of objects; Commonly known as “color fringing” or “chromatic distortion” in photography and optics.
Synonyms & Variants
aberasi warna
Another name for chromatic aberration; an optical defect in lens systems that causes different wavelengths to refract differently, producing colored edges or rings.
cacat kromatik
Term referring to an optical defect caused by color dispersion in a lens, resulting in blur or colored halos around objects.
dispersi lensa
Physical phenomenon where a lens's refractive index depends on wavelength, causing color separation and contributing to chromatic aberration.
efek pelangi palsu
A lay/popular expression for the appearance of colored rings or edges in photos or optical images caused by chromatic aberration.
Usage Notes or Etymology
The term aberasi kromatis derives from two Latin roots: aberratio (deviation, from the verb aberrare, meaning 'to wander from a path') and chromaticus, adapted from the Greek khroma (χρῶμα), meaning 'color'. The phenomenon was first scientifically identified by Isaac Newton in the 17th century, who observed that a single glass lens cannot focus all wavelengths of light at the same focal point. In modern photography and astronomy, this defect is corrected using achromat or apochromat lens designs that combine glass elements with different refractive indices. In Indonesian scientific literature, the term is used as the standard formal designation in optics, physics, and professional photography.
